Permanant link create for revision which is not latest does not work

While trying to Export the permanent link of the revision which is not latest and opening the link in a new browser, the link does not work.

Steps followed.

1. Open any revision which is not latest from the manta flow viewer and view the lineage in Manta flow viewer. 

2. Once the lineage is available, create a permanent link from the Export option from the Left Top of the lineage view (Export-> Create Permanent Link) 

3. Use the same link and open in a new browser, the link open and throws an error: Selected elements do not contain any relevant start nodes. Please, select different elements and try again. 

Actual: Opening the link throws an error

Expected: On opening the link, the lineage view should open.

    This is intended functionality. We can only guarantee that the name, type, and parental path of an asset won't change. This ensures that if you use a permalink in the future, even with a completely separate version of Manta or any other changes, it will still direct you to the same asset as long as the instance is scanned again, as the link uses the path directly.

    There is no reference to a specific date, time, or revision within the link. This is a fundamental issue with using revision numbers as the positional argument for lineage timing. We can't guarantee that, for example, 'Revision 7' corresponds to a specific date in 2008. If you uninstall Manta, reinstall it, and rescan, the version you want to see might now be 'Revision 2.'

    This problem will be addressed in the new version of Manta. Instead of using revisions, we will use the date and time of ingestion for lineage, which is a more stable reference point. This way, if the same hierarchy and path exist anywhere else with the same date and time, we can provide a reliable permalink.

    It's worth noting that in the current version of Manta, if you want to create a link to a specific revision and asset, you can add the asset and render it in that revision, then copy the URL that appears when you're in the viewer. However, if you uninstall and reinstall Manta, or wipe the database, this link will no longer work in a new version of Manta because it relies on revision dependencies and asset IDs specific to that particular installation. This is why it's not a perfect long-term solution, but this issue will be resolved in the upcoming product version.
